Once awakened, after killing Dayu for no longer being the player whose music he loved, Doukoku demands to face Kaoru as she appears. As Kaoru readies the sealing character, Super Shinken Blue, Hyper Shinken Green, and the other Shinkengers keep Doukoku from her. Just as the vassals are defeated, Kaoru successfully unleashes the Sealing Character Gedou Seal on Doukoku. But the sealing character fails as Doukoku reveals that he absorbed Dayu's human aspect to protect himself. Doukoku nearly kills Kaoru, but Takeru covers their escape. Later that night, Kaoru requests a private audience with Takeru. Admiring him for having such loyal friends and seeing that the plan she was brought on for failed, Kaoru adopts Takeru as her son and successor, resigning as head of the Shiba House. This makes Takeru the nineteenth head of the Shiba House, and once more leader of the Shinkengers. Meanwhile, after Doukoku pays his final respects to Dayu, he begins his attack on the mortal realm as the Sanzu River overflows into the living world. With Takeru announcing a strategy of all-out battle, the Shinkengers march towards their final confrontation with renewed confidence.
